HINGE. f

SPECIFICATION forming 'part ofl Letters 'Patent NI'O.v 283,27*?,dated August 14,` 1883.

' Application tiled January 15, 1883. (Modelf) To all whom it may concern.-

Be it known that I, ALONZO Il. PORTER, a citizen of the United States, residing at Chi cago, in the county of Cook and Stateoflllinois," have invented anew and -us'eful Strap-Hinge; and I do hereby declare that the following is a full, clear, and exact description of the same,

tion of parts illustrated in the accompanying drawings, in whichi connect the hinge members together.

Figure 1 is aperspective view of my im* proved hinge. i Fig. 2 is an elevation of the same. v

As shown in the drawings, Iny` improved hinge consists of two members, AA, of theusual shape, provided with pivoteyes a of, through which the pintle or rivet B passes topivotally Ihe pivot-eyes a a are each made one-half the Width of the hinge, and may have a lap, a2,

riveted to the main portion'of the strap, as

shown. Any other suitable mode of forming such eyes may be used without departing from the spirit of my invention. The members or straps A A ofthe hinge are formed with a turned edge or iiange, C Cf, the iiange `of the one being at the `top of the hinge and of the other at the bottom, as shown. This improved construction admits of the members ofthe hinge being made alike-a feature in manufacture and use that possesses marked advan- 4o tages.

In order to brace and support the ends of the pintle or rivet B, which are otherwise left unsupported bythe halved construction of the to receive the ends of said pintle or rivet, and support and brace the same in a very effective manner.

My improved construction of hinges, as above described, permits of the use of lighter material in construction, and yet be as strong and durable as an ordinary hinge of much heavier construction, these merits being due to the iianges or turned edges C C,whichbrace and stiften the parts in a very eii'ective manner;A

I am aware that priorto my invention strap- `pivot-eyes, as shown, I extend the flanges or turned edges, so as to form supporting-eyes c c' hinges have been made with iianges 'or turned edges at both sides of their members or straps, so as to impartstiffness to .thev same. I therefore do not claimsuch construction, broadly,

blib

What I do claimas myinvention, and desire .to secure by Letters Patent, is-

The leaves AA A of a strap-hinge, formed alike and interchangeable, with the pivot-eyes formed in halves, as set forth, and turned edges or ilanges C C', having projecting ends that form'supporting-eyes for the ends of the hinge pintle or rivet, all constructed and arranged as herein described, and for the purpose set forth.

ALONZO L. PORTER.
